SEOUL, September 7 (Yonhap) --The perfectly round-shaped full moon will rise on the upcoming Chuseok, September 10, Chungju Goguryeo Astronomical Observatory announced on September 6.

According to the Astronomical Observatory, the moon is the roundest when the sun, earth, and moon come in a straight line

On the other hand, since the moon orbits an oval orbit, there are occasions where the sun and Earth are unable to form a straight line, even on the fifteenth day.

In extreme conditions, the sun and the earth form a straight line only on the fifteenth day, and finally form a full round-shaped moon.

This Chuseok full moon will have a perfectly round shape from the time it rises.

The moon will rise at 7:04 p.m. in Seoul. At 6:59 p.m., five minutes before the moon rises, the sun and the earth will meet on a straight line, leading to a perfectly full moon.

In the case of the east coast, such as Gangneung and Sokcho, it appears on the horizon as a round shape at the same time as the moonrise.

Director Lee Tae-hyung from the Chungju Goguryeo Astronomical Observatory stated, "The full moon that rises on Chuseok will have the roundest shape at the time of the moon's birth among the full moons of Hangawi that have appeared in the last 100 years."

The Chungju Goguryeo Astronomical Observatory will be hosting a Moon-greeting Festival on September 9, the first day of Chuseok, with the theme "Moon Moon Bright Moon."

Visitors will get a large moon poster with Korean rice cakes, Songpyeon, and get more souvenirs through games like Matching the Moon Landing Darts and the Tuho game.

At 7 p.m., Director Lee will be giving a free speech about the full moon with the title "Moon Moon Bright Moon."

During the night observation time, which begins at 7:30 p.m., it provides an opportunity to directly observe the moon, Jupiter, and Saturn with a telescope.
